A general object of the invention is to provide an attractive article ofthe nature described comprising a cap section vhaving a dispensingopen-r ing and a base-'section Vboth sections lincluding cooperatingelements for expelling avcreamy substance through the dispensingopeningwhen one While devices of this general nature have-been heretoforeproposed;nevertheless, they have not-come into general use because they'frequently leak or the parts accidentally become separated to spill orexpose vthe contents.

Accordingly, one of the objects' of -theinvention is -to provide acontainer construction which lends itself to convenient manufacturingpractices, and includes mating sections having cooperating meansfor-being interlocked by mere assembly and partial rotation,'as wellaseffective vmeans-for sealing the sections after they areonce assembledand relativelyV rotated-to compress and expel the' contents. y

Another'object is to provide simple and reliable means-forlocking-thesections against being returned to their voriginal point ofassembly so that they cannotcome apartor be separated'for reuing.

A further object is 'to provide a construction which includes a 'minimum`numberA of parts thereby-making a dispenser which is' economical to'manufacture and Vreliable in use.

vWith the above and other objects in view which will more readily appearas the nature of theinvention is better understood, the same consists inthe novel construction, combination, and arrangement of parts,hereinafter more fully described, illustrated and claimed.

A preferred and practical `vnenribodiment of the invention is shown inthe accompanying `drawings, in which: Y

' Similar reference characters designate-corresponding parts throughoutthe several figures of the drawing.

Referring rst tothe embodiment-of the invention shown in Figures 1 to6,'inclusive, itwill be observed that the same vessentially includes inits organization a cap section A anda base-section B, respectivelyincluding sidewalls I and 2 adapted to be interiitted in telescopicrelation,

and each being provided externally with 'indexing ribs 3 and 4 ortheirequivalent to facilitate initial assembly and subsequently serve asa signal to indicate the lcontents remaining in thecontainerafteruse-has once been started. The said indexing elements arealined-to eiiectinitial assembly and after partial rotation of thesections never returnvto this relation because of locking meanshereinafter described.

VThe cap'section A is provided'with a dispensing opening or hole 5radially alined with the indexing element 3 and located in afinger-receiving depression or well 6. 'I he under face of the coverA'isalsofprovided with a downwardly projecting pin 'I which is angularlyoff-set vwith respect'to the hole E as shown in Figures 2 and 3 andintended to engage with the hook portion '8 of a radially disposedpiston vane 9v which is formed at its inner end with an eye lil forfitting over` a post I l axially carried bythe interioriace of the base2. The vane`-9 therefore,lcan rotate relative to the base. Said base Bis'also provided with anvintegral radiallydisposed abutment l2 in theform' of a wall which, like thevpiston vane 9, is coextensive in heightwith-the space. between the inner surfaces of vthe Ncap and base. Itwill also be noted that the length of the vanev Qiand the abutment I2are 'substantially the same so that when considered'in connection withthe post Il, completely span the radial distance between the p-ost andinterior face of the side walls l and 2 of the cap and base. When thepin 1 is engaged with the hook 8 ofthe'vane it will be apparent thatrelative rotation ofthe cap Ayto the base B will'cause movement of thevane "9 with're'spect to theabutment I2 so that 'the 'material M(Figures 4 kand 6) will be expelled through the discharge opening orhole 5 into the well 6 of the cap as indicated at M' in Figure 1. Thehole 5 and pin l being in angular relationship, and the hole 5 beingdisposed relativelyin advance of the pin when the pin 'I is engaged withthe vane 9, the latter will, of course, when moved by the pin, cause thematerial in front thereof to pass through the opening 5 since thematerial M is trapped in the space between the cap and base against theabutment wall I2.

Referring now more particularly to the means of holding the sections Aand B together for rotary movement as well as against separation, it maybe first noted that the vane 9 preferably carries a locking element I3in the form of a light leaf spring which is secured at one end to therelated face of the vane 9 while its opposite yielding endengages theinner face of the side wall 2 of the container. This spring 1.?, isintended to cooperate with a locking element Ill in the inner face ofthe side wall 2, and which, in the example shown, is in the form of anotch formed in the side wall to provide a locking shoulder I5.Obviously, however, instead of making the locking element in the form ofa notch depressed into the side wall of the base, it may be in the formof a raised tooth with the same general locking effect.

The inner face of the side wall I of the cap A is provided with thediametrically disposed pairs of ribs I6 and II. These ribs are intendedto pass through corresponding pairs of notches Ilia and I'Ia in theupper flange portion I8 of the base, said flange portion I8 havingitsouter face provided with an annular recess or channel I9 whose upperside wall constitutes an abutment or track against which the pairs ofribs I6 and I'I bear when the sections A and B are rotated relative to ieach other.

As previously indicated, the ribs I6 and I'I which cooperate with thenotches Ia and Ila on the base are so related to the indicator ribs 3and i that, when said ribs are in vertical alinement as shown by thedotted line and solid line positions of 3 and 4, respectively, in Figure1, the ribs I5 can readily enter their related notches Ia in the base.Likewise, when the sections A and B are thus assembled the pin I engagesthe hook 8 of the vane 9. Upon moving the cap A in the direction of thearrow shown in Figure 1, the

said sections A and B not only become interlocked for further rotarymovement to performthe operation of expelling the contents with the aidof the elements 9 and I2; but, also, the spring locking element I3 ismoved sufficiently so that it passes beyond the locking element I4. Oncethe sections A and B are initially rotated relative to each other,continued rotary movement between the same is possible until thecontents of the dispenser have been exhausted. Of course it is possibleto rotate the elements A and B so that the vane 9 may idly move backsubstantially to its original position. However, due to the spring leafI3 and locking element I4, it will be impossible to bring the ribs I6and I'I back into registering relation with notches Ia and I'la. Thus,after the parts have been once assembled and a portion of the expellingmovement of the vane has taken place, it will be impossible for thesections to be subsequently separated yfor the purpose of effecting arell of the material.

Another distinctive feature of the construction shown in Figures 1 to 6is that the cap A and base B are provided with suitable sealing means toprevent the escape of the paste or cream un- 4 der pressure. In theexample shown this sealing means preferably consists of an annularcollar 20 on the inner face of the cap and spaced inwardly from the sidewall of said cap so as to lit in a complementary recess 2| in the flangeI8 of the side wall 2 of the base.

In the construction shown in Figures 1 to 6 inclusive, the sections Aand B having the characteristics described are preferably made fromplastic material lso that they can both be readily made by a convenientstamping, molding, or-' pressing operation. The parts A and B togetherwith the piston vane 9 constitute all of the movable parts of thedevice. Thus, the simplicity of the invention from the standpoint ofmanufacture and use becomes apparent.

Figure 6a illustrates a modification of the invention above describedwherein the piston vane 9a is made integral with the cap section A, andthe abutment I2a is likewise made integral with the base section B. VItWill also be observedthat the post I la and abutment I2a may beintegrally formed or connected so that the piston vane A9a carried (bythe cap section A may exert adequate pushing force against the contentsof the container with respect to the abutment and post. In this form ofthefinvention all of the means for interlocking the cap and basepreviously described are adhered to. The difference between theconstruction shown in Figure 6a and that shown in Figure 6 is that'themovable vane 9 of the latter gure is made integral with the cap sectionthereby eliminating the metallic vane as a separate element, andlikewise, the locking means I3, I4. I5 of Figure-6 is omitted from theconstruction shown in Figure 6a.

A modication of the invention is shown in Figure 7 wherein the devicemay be made of transparent plastic material and cap section A and thebase section B have their side walls I b and 2b telescopicallyintertted, while the base section B is interiorly provided with anintegral abutment wall I 2b and the cap section A has integrally formedtherewith the piston vane element 9b. In this form of the invention thecap section A is formed with a dispensing or discharge hole 5a, and thepiston vane 9a as well as the abutment wall |2b terminate at their innerends at a point short of a central pivot element 22 for pivotallyconnecting the sections together. This pivot element may assume variousforms but preferably consists of a tubular shell having a head portionat one end for engaging the outer face of one of the sections while itshollow interior is threaded to receive a cap screw 23 whose head engagesthe outer face of the base. Thus, the pivot 22 serves as a fastening forholding the sections Aand B against accidental separation. In thisarrangement the base section B would be lled with cream .or paste andthe piston vane 9b and abutment wall I2b assembled in juxtaposedrelation so that, as relative movement occurs between the sections onthe element 22 as an axis, the movement of the -vane relative to theabutment will expel the material through the discharge opening 5a. Inthis form the inter-engaging means on the cap and base as per Figures.A1 to 6 linclusive is unnecessary because of the fastening 22. f

From the foregoing it will be apparent that the invention provides acontainer for creamy or pasty material from which the same may bedispensed inn the form of a cylindrical ribbon through the cap section,as desired, thereby making it possible readily lto obtain Yasmall amountof the material in a convenient way, while at the same time preservingthe remaining contents for future use.

Without further description it is thought that the advantages of theinvention will be readily understood by those skilled in the art andwill, of course, be apparent that changes can be resorted to within thescope of the appended claims.
